Don’t get confused with saltwater pom pom crab
Saltwater pom pom crab (scientific name Lybia tessellata or Lybia edmondsoni) is a species of small crab in the family Xanthidae. They live in shallow sea in the Pacific Ocean, mostly Haiwaiian Islands or tropical Indo-Pacific Ocean.
Freshwater pom pom crab (scientific name Ptychognathus Barbatus) is a species of crab in the family Pinnotheridae. Freshwater pom pom crabs can be found throughout Southeast Asian, Taiwan & southern Japan.
Saltwater pom-poms are much larger than freshwater, and require a specialized tank. They can grow up to 6 inches across! Salt water pommes may look like freshwater ones at first glance but they have different colors and patterns on their carapaces (hard shell) that set them apart from the freshwater family. The two crabs are also night and day in their behavior: saltwater poms live deep at the bottom of your tank and they like to stay there, whereas freshwater ones will try to climb out of your aquarum.
Saltwater pom pom crab also have longer legs & slimmer claws. Because saltwater pom-poms live in shallow ocean beds, near coral reefs, they developed more colorful shells, compare to more brownish yellow freshwater pom pom crabs.
Keeping freshwater pom pom crab is an undemanding task
And I mean freshwater pom pom crabs are really not picky with their living conditions. You can throw them in a fishbowl, add some fine sands as substrate, add some tap water, and they’ll thrive. Add some decorations & plants, they’re will be happy for life.
The only thing you need to do is give them fresh water every day, feed them some pellets from time-to-time, and make sure the temperature doesn’t get too high. The tank water should be around 68° – 78° F (20° – 25° C), which is very easy to maintain.

The freshwater pom poms are a great choice for those who have shallow or nano aquariums. They are small crabs, reaching a maximum size of just over an inch. They also have beautiful colors and get along well with other species in the tank.
They can be kept alone or in pairs because they don’t grow large enough to fight for territory like their saltwater counterparts do.

Freshwater pom pom crabs are not picky with their foods
In natural habitat, freshwater pom poms eat a wide range of food, such as insects, worms and small crustaceans. Freshwater pom pom crabs also feed on a wide range of algae, including those that are unpalatable to other crabs.
In captivity, freshwater pom pom crabs have a wide range of diet. They can be fed with freshwater shrimp pellets that are specifically designed for bottom feeder, or algae waffers, and various of live feeds. Remember to change water in your aquarium regularly to keep the water clean.

Freshwater pom pom crabs are new addition to the aquariums community. There are a lot of knowledge for this little specie that we haven’t yet understood.
Freshwater pom pom crabs, as their name, are known to live in freshwater environment, especially stream or lake. However, there are indications that they breed or lay eegs in saltwater environment or in brackish water.
There isn’t any well-researched document that record the reproductive process of freshwater pom pom crabs.
Pom pom crabs also need calcium supplements
Just like any other crustaceans, freshwater pom pom crabs also go through the molting process. During this molting process, they will shed the old shell to let their body grow larger. This process is essential for pom pom crabs, and they usually go through this process once a year.
The molting process requires a large amount of calcium. And in captive environment, there are many freshwater pom pom crabs not getting enough calcium.
This, in turn, will lead to stunted growth and reduced life span. So it is essential for owners of these animals to provide them with a diet that includes ample quantities of calcium supplements such as oyster shells or crushed eggshells.

Freshwater pom pom crabs like to hide and burrow. They enjoy digging into the substrate of their aquariums, and they will often do this during molting season so as to avoid any injury that might happen while shedding its old shell. One way owners can help is by providing a hiding spot for them with some driftwood or stones in it – these freshwater animals love hiding behind things!

They are generally resistant to illnesses
Since freshwater poms are such unique critters, they’re also resistant to illnesses that often plague other types of crabs. For example, the freshwater pom is safe from vibriosis and necrotizing hepatopancreatitis – two common diseases found in saltwater crabitat systems!
